Store Two Related Numbers In A List?
Sep 21, 2010
Is it possible to store two related numbers in a list and then check them if the are exist in the list?ere is an example of what I did to achieve the above:
Dim CounterConnections, FromN, ToN As Integer
Dim ConnectionsList As New List(Of Integer)
Dim Myrandom As New Random
[code]....
The above code generate two random numbers and store the in a list. I am adding the two numbers to be one so that I can check if they exist in the list.e.g. if the FromN = 7 and ToN = 11 then the list will consist of :
711 and 117
a list to store 11 7 and 7 11 which is capable to be checked later if some some numbers are exists.

So how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:
dim num as integer
dim r as new random
num = r.next(1,5)
if num = 1 then
elseif num = 2 then
etc.
That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open. It brought me inside of the folder so I tried to open the game but there is no form1 there. It says the games name then .exe in the explorer-like thing in the top right?Also, how would I have a value or something in a label and access it from a button.
Example:This is in a label.
Dim number as Integer
number = 0
Then in the button do
Label.number = 0
How would I do something like that? I want to use that a lot as I did in a different language.

I have a table being imported into my VB application that has 3 columns. I have written code to import the table, and have written code to display on the first column (country) in a list view.
What I want to do now is have the user select / highlight an item in the list view, and have the third column (currency) related to that selected country appear in a text box when a button is clicked.
Here's the code I've written that successfully imports the data and displays the first column:
Private Sub frmCountry_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim dataCountry As New DataTable()
[Code]...
Should I perhaps use something other than a list view?

I currently have a list of words in a text file sorted in to alphabetical order and put into lower case, but I would like to be able to also display the line numbers on which these words are associated with.. but only one instance of.
For example,
"This is a random text
file that I
have just made
up this second"
[Code].....
As you can see above, I would like to show that "this" for example appears on line 1 and 4. Hopefully tabbed so that it keeps a nice look to it.

I'm looking for a way to take seven 2 digit numbers & combine them into one number to store in a database.The numbers represent hours for each day of the week & I only have one field to store them in. Then I need to be able to take the stored number & decode it back into the original seven numbers. Anyone have any clever ideas how I can do this?

Right so my generator is working, but I now want to take the numbers that it generates and add them to a list of generated numbers. So you can monitor what numbers have been generated. then ideally a way to exclude these numbers from being generated again.

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()

I just wondering if Visual Basic.NET and VB6 can do these examples.I have use python before and i will take some examples.Save numbers to a list and add
Quote:
this_is_a_list=[1,2,35,4564,532,2454,3404,3,455,2,1]
x = len(this_is_a_list)
this_is_a_list.insert(10, x)
len is a function who count how long a list is. This list is 11 numbers long. I will now insert/add number 10 after the last number. The first number has the place 0. The second number has the place 1.Can VB.net do that? Check how long a list is?Delete a list?

In .NET which data type do you use to store list of strings ?Currently I'm using List(Of String) because it's easier than Array to manage and add/remove stuff. I'm trying to understand what are the other options, when they become handy and when I should avoid List(Of String) usage.

I have a WPF form that takes a list of objects that have locations and sizes and plots them on the canvas. I'm currently trying to implement an undo button that will throw out all the changes that have been made to the positions of the objects and revert back to the original collection that was retrieved when the form loaded.
As it stands now I go out to the database on the load of the form and get all the objects that will need to be displayed then assign the list that is returned to two seperate collections. The problem that comes up is that the two collections are actually pointers to the original collection and whenever one is changed the changes are reflected in the second collection.
Is it possible to copy a list of objects so that changes made to one collection won't affect the secondary collection?
So far I've tried simply using the assignment operator, passing the source collection into a function byval and scrolling through each element of the list manually adding it to the second collection and using linq to get all the objects from the original list and pushing the results to a separate temporary list and assigning the second collection to the temporary list.
I feel like I'm overcomplicating the issue but almost all the places I've come across while googling say that this behavior is by design, which I understand but it seems like this would be a fairly common idea.

I have a list of files and all of them have a different size. I need to upload them in chunks of 250Kb (or less if it's a small file or if it's the last chunk of a file).What I would like to do is read a bunch of chunks (lets say 15 chunks), in a separate thread, and then store the chunks of data in some sort of list. This list must be available to other threads.
An upload thread (I don't need help with uploading itself) takes the first chunk from the list and marks the chunk as "currently being uploaded". When the chunk has been fully uploaded, then the chunk is removed from the list. A second upload thread takes the next available chunk in the list that has not been set to "currently being uploaded", etc. There are a total of 10 upload threads working at the same time.
As soon as a chunk is removed from the list, then a new chunk of data is read and added to the list.Does anybody know what kind of list I need or how I should do something like this? I don't expect people to write out the code for me, but I have no idea where to start with this.

I have a .txt file i want to read that has states by abbreviation and states by name. In that text file some are territories and some are states.
I want to read from that file and put the abbreviations into one structure array and the states into another structure array.
I then want to lookup up the states by abbreviation or state name. The lookup will simply be selected by a radio button which will flag either the states full name array, or the abbreviation array.
all I have is the structures created:

VS2010
VB
I would like to be able to add every combination of a list of numbers to determine which combinations equal a specific result.
Simple Example:
List: 2, 4, 6
Result: 10
How many and which combinations of numbers result in the number 10? The correct anwser is only one which is 4 + 6 = 10. The example is simple but the actual list may contain as many as 10 - 15 decimal numbers.
I have thought of the following as a possible way of checking each combination by using binary:
- There are 3 total number so the possible combinations would be:
123 - Three numbers
000 - Add no numbers
001 - Add the last number
[Code].....
However, I don't know how to actually match up the bitwise bits to the numbers in the array to actually add. Example:
101 - I should check if 2 + 6 != 10 per the example above so this wouldn't satisfy the result... does this make sense? The answer would be 4 + 6 = 10.
how to check and add all combinations from a list of numbers to determine if the result is a specific number?
